Scripts for calculating groundwater recharge via a stochastic vadose zone water budget

This archive contains code related to the Open Source scientific computation software GNU Octave for a stochastic vadose zone water budget. A range of groundwater recharge estimates is generated using a Monte Carlo approach based on stochastic spatiotemporal rainfall variability and empirically-derived temporal evapotranspiration variability. This project is useful for calculating the uncertainty in recharge rates due to spatiotemporal variability in rainfall and annual variability in actual evapotranspiration. Including the spatial/temporal variability in rainfall reduces the uncertainty in precipitation and therefore uncertainty in recharge for a multi-decade water budget.

本档案收录了与开源科学计算软件GNU Octave相关的代码，该软件用于随机性土壤蒸发带水分收支的计算。通过蒙特卡洛方法，基于随机时空降雨变率和经验推导的时空蒸散变率，生成了多种地下水补给估计值。此项目对于计算因降雨时空变率和实际蒸散年际变率导致的补给率不确定性具有重要意义。将降雨的时空变率纳入计算，能够降低降水的不确定性，从而减少多年期水分收支的补给不确定性。
